Description
Technical Field
The invention relates to the technical field of building construction, in particular to a construction method of a water stop.
Background
The urban underground comprehensive pipe gallery is a pipeline public tunnel built underground in a city, more than two municipal pipelines such as electric power, communication, gas, water supply, heating power, drainage and the like are intensively laid in the tunnel, and the originally separately laid gas pipes, rainwater pipes, sewage pipes, high-voltage electric wires and the like are intensively laid and are parallelized, and all the pipelines are brought into the comprehensive pipe gallery engineering. The underground comprehensive pipe gallery solves the problems of 'link pulling' and 'spider web' in the air caused by the maintenance and expansion of various pipelines in the urban development process, and plays a positive promoting role in improving the overall image of the city and creating the urban harmonious ecological environment. With the expansion of urban areas and the development of construction, the advantage of building underground comprehensive pipe galleries is gradually confirmed by relevant government departments.
Due to the fact that the types of pipelines in the underground comprehensive pipe gallery are various, if important pipelines such as high-voltage cables, weak current, communication transmission, fuel gas, water supply and sewage exist, the phenomena of corrosion and ignition of connecting pieces are easily caused by moisture and water inflow, and the safe use of the pipelines is affected. Therefore, the underground comprehensive pipe gallery has extremely high requirements on water resistance, and the deformation joint of the underground comprehensive pipe gallery is a waterproof weak link due to the structural reason, and a water stop belt is usually buried in the deformation joint for sealing and water stopping. The installation quality of the water stop directly influences the waterproof and water-stopping effects.
The waterstop usually needs to be placed in the middle of a wall body, and when the waterstop is installed, reliable fixing measures need to be taken to prevent displacement when concrete is poured. Most of the existing fixing modes need to perforate and perforate the allowed part of the water stop belt, and the hole has slight deviation, so that the effective waterproof part of the water stop belt can be damaged, and the sealing and water stopping performance is influenced.
Disclosure of Invention
Aiming at the defects of the prior art, the technical problems to be solved by the invention are as follows: how to provide a construction method of a water stop belt, which is simple and convenient to operate, can prevent the water stop belt from being damaged and ensures that the water stop belt is positioned at the central position of a wall body during concrete pouring.
In order to solve the technical problems, the invention adopts the following technical scheme:
a construction method of a water stop is characterized by comprising the following steps:
s1: firstly, obtaining a water stop fixing device with the following structure, wherein the water stop fixing device comprises templates and split bolts, the templates are used for being installed on two sides of a wall to be poured, and the split bolts are used for connecting the two templates; a first baffle and a second baffle which are arranged oppositely are respectively arranged on the two templates, the width directions of the first baffle and the second baffle are both vertical to the templates, and the length directions of the first baffle and the second baffle are both arranged along a deformation joint to be constructed; one side of the first baffle, which is opposite to the second baffle, is provided with a positioning groove which is arranged in a penetrating way along the length direction; a convex rib arranged corresponding to the positioning groove is arranged on one side, opposite to the first baffle, of the second baffle, and the width of the convex rib is smaller than that of the positioning groove; the width of the part of the first baffle plate between the two templates is consistent with that of the part of the second baffle plate between the two templates and is matched with half of the thickness of the wall to be poured, so that when the two templates are installed in place according to the thickness of the wall to be poured, the water stop belt can be extruded and fixed between the convex edge of the second baffle plate and the positioning groove of the first baffle plate;

In the structure, the width of the positioning groove is larger than that of the convex ridge in the middle of the water stop belt, and the depth of the positioning groove is larger than that of the convex ridge in the middle of the water stop belt; after the convex edge of the water stop belt is extruded to the positioning groove by the convex edge of the second baffle, the water stop belt is extruded and deformed into a V shape by the two sides of the positioning groove, and is fixed between the first baffle and the second baffle in a basin shape.
Further, in step S1, the second baffle includes two side plates disposed in parallel at intervals, and a top plate slidably disposed between the two side plates, the top plate protruding outward toward one side of the first baffle to form the protruding rib; two one side fixed mounting that the sideboard deviates from first baffle has the bottom plate, have on the bottom plate just to the screw hole that the roof runs through the setting, install the orientation on the screw hole the bolt that the roof set up, the bolt butt is in on the roof.
By adopting the structure, the top plate can be ejected out between the two side plates towards the direction of the first baffle plate through the adjusting bolt, so that the pressing force of extruding on the water stop belt is increased.
Further, in step S1, the top plate has a plurality of guide grooves formed through both sides in the thickness direction thereof and a guide rib formed to fit the guide grooves on one side of the side plate facing the top plate.
Further, in step S1, the first baffle and the second baffle each have a plurality of mounting holes uniformly distributed along the width direction, and the first baffle and the second baffle are respectively mounted at the end portions of the corresponding templates by bolts passing through the mounting holes.
By adopting the structure, the mounting holes are uniformly distributed along the width direction, so that the width of the part, between the two templates, of the first baffle and the second baffle can be adjusted through the mounting holes at different positions, and the wall body with different thicknesses can be adapted to, and the adaptability is improved.
Further, in step S1, rubber anti-slip strips are disposed on opposite sides of the first baffle and the second baffle.
Therefore, the friction force of the positioning clamp in the process of clamping the water stop can be increased, the water stop is prevented from falling off, and the positioning reliability is improved.
In conclusion, the water stop strip has the advantages that the water stop strip can be ensured to be positioned in the middle of the wall body during concrete pouring, the formwork is convenient to erect and dismantle, the water stop strip is prevented from being damaged, the service life of the water stop strip is prolonged, the waterproof performance is improved, and the like.
